SAFETY INTERLOCK SYSTEM4.2

The mower is equipped with an interlock system

intended to protect the operator and others from injury.

This is accomplished by preventing the engine from

starting unless the deck drive is disengaged, the parking

brake is engaged and the neutral lock lever is in the

neutral lock position. The system shuts off the engine if

the operator releases the left hand steering lever with

the deck drive engaged, the operator releases the left

hand steering lever with the neutral lock lever in the

drive position (D) or if the neutral lock lever is placed in

the drive position (D) and the parking brake is applied.

Never operate equipment with the interlock system

disconnected or malfunctioning.

WARNING

Never operate the mower with the interlock

system disconnected or malfunctioning. Do not

disengage or bypass any switch; injury to yourself

and others or property damage could result.

GROUND TRAVEL AND STEERING4.5

- IMPORTANT -

If you are not familiar with the operation of a

machine with lever steering and/or hydrostatic

transmissions, the steering and ground speed

operations should be learned and practiced in

an open area, away from buildings, fences, or

obstructions. Practice until you are comfortable

with the handling of the machine before attempting

to mow. Learn the operation on flat ground before

operating on slopes.

- IMPORTANT -

Start practicing with a slow engine speed and slow

forward travel.

Learn to feather the steering controls to obtain a

smooth operating action.

Practice operating the mower until you are

comfortable with the controls before proceeding

to mow.

FORWARD TRAVEL

To travel forward with the mower, disengage the parking

brake, place your hand on the left hand steering control

while placing the neutral lock lever in the drive (D) position.

Slowly push the steering control levers forward an equal

distance. The further the steering control levers are pushed

forward, the greater the forward speed will be. To increase

the speed, push the steering control levers forward and

to decrease speed, pull the steering control levers back.

See Figure 4-2.

To stop the forward travel completely, pull the steering

control levers back to the neutral position.

To steer the mower to the left while traveling forward,

pull the left steering control lever back. The further the

steering control is pulled back, the quicker the mower will

turn left. See Figure 4-3.

To steer the mower to the right while traveling forward,

pull the right steering control lever back. The further the

steering control is pulled back, the quicker the mower will

turn right. See Figure 4-3.

- NOTE -

Smooth operation of the steering control levers will

produce smooth mower operation. While learning

the operation of the steering controls, keep the

travel speed low.

REVERSE TRAVEL

CAUTION

Disengage power to the mower before backing

up. Do not mow in reverse unless absolutely

necessary and then only after observation of the

entire area behind the mower.

CAUTION

Before backing up, observe the rear for persons

and obstructions. Clear the area before backing

up. Possible injury or property damage could

occur.

To travel in reverse, pull both steering control handles

back. Keep the travel speed low while traveling in

reverse.

- NOTE -

The mower may not travel straight in reverse.

Slight adjustments may need to be made using

the steering controls.

To steer left while traveling in reverse, allow the left

steering control lever to move forward. The further

the control is allowed to move forward, the quicker the

mower will turn left.

To steer right while traveling in reverse, allow the right

steering control lever to move forward. The further

the control is allowed to move forward, the quicker the

mower will turn right.

To stop the reverse travel, allow the steering control levers

to return to the neutral position. If the mower is to be

parked, engage the parking brake and place the neutral

lock lever in the neutral (N) position.
